Manufactured from solid PTFE, these safety covers provide an insulating barrier between the user and Teflon Heating blocks. Tests show that the temperature difference between the outside surface of the PTFE cover and the  block can be as much as 100°C  reducing the temperature of exposed surfaces by as much as 50%. These Solid PTFE Safety Covers reduce the risk of users touching a hot Heat-On block and provide the added benefit of lowering energy consumption Teflon heating blocks are simply the safest, fastest and most efficient way to heat and stir a round bottom flask from 10ml to 5 litres. Replace messy oil baths, heating mantles, avoid spills and make your. The insulating properties of PTFE Safety Covers mean that up to 15% less energy is required to maintain temperatures for extended periods
